We should be reeling from the Apple Event yesterday, but we're pumped up and ready to tell you all about some really neat stuff today. Firstly, there's a heart chip that might help scientists completely eliminate the need for drug testing on animals -- this would also cut the cost of developing those drugs. Then there's a company hoping to bring incognito, first-person sports cameras into the mainstream, which might change the way we watch professional sports. And finally, there's a 3D-printed violin that could double as a weapon in the next "Star Trek" film.

It's also time for a batch of new releases today, so get your wallets ready!
